Nothing is wrong with it, the comment was directed at the level of dedication that it showed. She was an average teacher, who was not motivated by inspiration to teach. It seems to me that most of the (conservative) teachers here at FR are the motivated kind of teachers we would love to have - I just don't think they are the norm. My neighbor is the norm.
Again, what's wrong with this? If the schools are set up so that she has free periods [I'm jealous], why shouldn't she use them for grading papers? It's obviously part of her job. What would you have her do during her free periods?
There's nothing wrong with it, the point is that she's representative of the vast majority of teachers (at least in my area) who absolutely do NOT put in 50-60 hours a week, with coming in early, staying late, and grading papers at home. If we had a rational structure for teacher salaries instead of the union structure, the people who put in additional time to be better teachers would be paid more while those who put in minimal time and got minimal results would be paid less. That's not the case though, and the current salary structure encourages those who would do less to go into teaching and discourages those who would do more.
That story doesn't pass the smell test. There are some critical details missing.
It's still a small town mentality here even though the population is becoming more small city. Also, she's a conservative in a liberal college town. Another friend of mine did get a job here, and she's definitely a party line whining teacher. She also was willing to take whatever job was open because her husband was often out of work.
